ELECTRIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 734,826, dated July 28, 1903.

Application filed March 4, 1903- or anode is of zinc and the cathode of carbon.

In the accompanying drawing is illustrated a battery or cell composed of a plurality of elements in accordance with the invention.

. In said drawing, l indicatesthe jar or cell,

which may be constructed of any suitable shape and material-snch, for instance, as

glass, porcelain, ebonite, or any other nonconducting material.

2 and 3 indicate the electrodes forming one component of the battery, the former of which is of carbon and the second of which is of zinc. A porous partition or diaphragm 4 separates the electrodes.

The carbon'electrode is immersed in nitric acid of, for example, 40 to 50 Baum and the zinc electrode in alcoholic solution of, for example, 5 to 15 Baum strength of pernitrate of mercury and potassium cyanid. As

an example of asuitable composition for said alcoholic solution, the following isgiven One thousand grams of alcohol of twenty-five per cent one hundred andfifty grams of nitric acid of forty-eight per cent-., ten grams of oxid of mercury, six grams of potassium cyanid solution of sixty per cent. The depolari- Serial No. 146,141. (No model.)

zer is separated from the solvent liquid by a very porous diaphragmfor example, a partition of fire-clay or the likewhich may be formed of a mixture of clay and pieces of carbon,which latter have been burned by heating the mixture.

Having now particularly described and as-- certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. An electrical element or battery the oathode of which is immersed in nitric acid and the anode in an alcohol solution containing pernitrate of mercury and potassium cyanid, the depolarizer being separated from the solvent by means of a diaphragm.

2. An electrical element or battery,the cathode of which is of carbon immersed in nitric acid of from to Baum, the anode of "which is of zinc immersed in an alcoholic solution of pernitrate of mercury and potassium cyanid, said solution having a strength of from 5 to 15 Baum; the said liquids being separated by a porous diaphragm.

3. An electrical element or battery having a carbon cathode in nitric acid, a zinc anode in an alcoholic solution of nitric acid, oxid of mercury and potassium cyanid, and a porous diaphragm separating said liquids.

In testimony that I claim the foregoing as my invention 1. have signed my name inpresence of two subscribing witnesses.

HENRY osANYI.
